Antenna switching devices, systems, and methods
First Claim
1. A wireless communication apparatus, comprising:
- a plurality of antennas including a first antenna and a second antenna;
at least one receive circuit including a first receive circuit; and
a controller configured to;
during a plurality of predetermined wake-up periods, receive a page channel via the first antenna, wherein the plurality of predetermined wake up periods are negotiated with a network for waking the apparatus from a sleep period according to a predetermined wake-up cycle;
wake up from the sleep period during a measurement period, to monitor one or more performance characteristics of the first antenna, wherein the measurement period comprises a period of time occurring outside of the plurality of predetermined wake-up periods; and
selectively switch to receive the page channel via the second antenna based on the one or more performance characteristics of the first antenna.

Abstract
This disclosure provides systems, methods, and apparatus for antenna switching. In one embodiment, a wireless communication apparatus is provided. The wireless communication apparatus includes a plurality of antennas including a first antenna and a second antenna. The wireless communication apparatus further includes at least one receive circuit including a first receive circuit. The wireless communication apparatus further includes a controller configured to selectively switch the first receive circuit from receiving wireless communications via the first antenna to receive wireless communications via the second antenna if one or more performance characteristics of the first antenna are below a threshold in one or more measurement cycles, the one or more measurement cycles including a wake-up cycle outside of a predetermined wake-up cycle. Other aspects, embodiments, and features are also claimed and described.
